DECORATORS APPLIANCE.

Specification of Iletters Patent. t t June 27, 191

Application filed May 6, 1914. Serial No. 836,686.

T 0 all whom it may concern:

Be it known that I, JOHN KAEFER, a citizen of the United States, residing at Hamilton, in the county of Butler and State of Ohio, have invented new and useful Im provements in Decorators Appliances, of which the following is a specification.

The invention has for its principal object the increase of facility in manipulation and adjustment of pottery and other articles in course of decoration or other treatment.

A particular aim is to give an improved means for engaging and securing an object in a coaxial position on the supporting plate which in the present instance comprises the usual disk, modified but applicable to use in the familiar ways heretofore practised.

It is also an aim to give a ready means for adjusting the device to hold objects of widely various shapes.

A further aim is to present means for ac curately spacing decorative details on an object without the necessity for making measurements.

It is a purpose to provide an arm rest of an improved form.

A valuable attainment of the invention is the provision of means to hold a stencil or stencils of various kinds which will also serve as a straightsedge and will be cooperative with the arm rest.

Additional objects advantages and features of invention will appear, some of which will be apparent in the construction, arrangement and combination of parts hereinafter described andshown in the drawings, where Figure 1 is a perspective view of the device inuse, Fig. 2 is a bottom view of the table disk, Fig. 3 is a detail view of the arm rest, Fig. 4: is a vertical sectional view of the mounting of the disk, Fig. 5 is a detail of the spacing device. Fig. 6 is a detail view of the straight edge and mounting.

There is illustrated a cast base frame 10, including the circular portion 11, having the concentric vertical shaft 12 fixed thereon, the upper end of which is conically finished for a reason which will appear. The shaft is circumferentially grooved as at 14 at a short distance from itslower end. Surroundin the shaft there is an anchor plate 15 also fixed to the base. This'and the at tachment of the shaft may be accomplished as shown by forming a tenon 12 on the lower end of the shaft threaded at its outer part, and inserted through a suitable opening in the plate and the base,on the lower side of the base a boss 16 being formed and engaging a nut 17 on the lower end of the tenon. The anchor plate is provided with any desired number of concentric series of apertures 18in this case, three ser1es each having a different number of openings and difierent intervals between the radii intersecting the apertures.

Engaged revolubly on the shaft there is a shaft 19, closed at its upper end and suitably formed thereat for ready rotation while supported on the conical portion of the shaft 12. A set screw 20 is engaged through a collar 21 fixed or formed on the 1 lower end of the shaft 19 the screw projecting through, the shaft also, at a height to engage in the groove 14, whereby the device is retained revolubly on the shaft. The collar 21 is provided with an extension 22 having vertical bores 23 therethrough arranged to register with respective series of apertures 18. Engageable slidably therein there is a sleeve 24 Fig. 5, having a transverse notch 25 in one side, and a shoulder 26 limiting its downward movement in the bores 23. A pin 26 is engaged revolubly in the extension 22, intersecting all the bores 23, and being cut away on one side whereby when turned to one position the bores 23 will be cleared, while in the other position, the pin will project across the bores, thus being adapted to engage in the notch 25 of the sleeve and hold it against removal from whatever bore it may be inserted. The sleeve has a spring-pressed locking pin 27 slidable therein and normally projecting through the lower end of the sleeve for engagement in the apertures 18, the pins 26 and 27 are each headed for convenient manipulation. Engaged revolubly on the shaft 19 there is a hub 28 in the form of a cylinder having a flange 29 at its upper end, its lower end being seated against the collar 21. A set screw 30 is provided by which the hub and shaft may be locked together. Attached to the flange and supported thereover in a plane at right angles to the axis of the hub there is a table disk 31, radial ribs 32 being formed on its under above the hub. The sleeve 24. carries a spur gear 32 just over the flange, meshed with gear sectors 33 pivoted on the under side of the disk 31 between the ribs 32. There are shown three of these sectors, and a corresponding number of arcuate slots 34 concentric to the pivots of respective sectors, the outer ends of the slots being closely adjacent the periphery of the disk and their inner ends being close to the gear 32. At what may be termed their outer sides the sectors are provided with threaded aper tures 35 alined with the respective slots in which apertures there are engaged in a suitable manner long screws 36 extending upwardly through the slots and having heads 37 on their upper ends adapted to engage objects to be decorated when moved inwardly thereagainst. The screws may project as far as desired below the disk, and will at all times be free for movement with the sectors. The heads of the screws may be padded or otherwise formed, and will serve to be grasped for manipulation, as well as to engage the article to be held.

It will be apparent from the foregoing that any article of symmetrical form may be accurately centered with great ease by simply setting it within the screws, upon the disk, the screws having been rotated properly to dispose their heads at the proper height to rmly engage the. article, and simply turning the disk while the spring pressed pin 27 is engaged with one of the apertures 18, the set screw 30 having been loosened. As the disk is turned in the proper direction, the relative change of position of the gear 32 will cause movement of the sectors, carrying the screws against the article to be held, after which the screw 30 is tightened to hold the object so engaged The reverse operation will release an object after decoration.

At the opposite end of the base 10 from the portion 11 there is an upstanding hollow arm 40, rectangular in cross section, a slot 41 being formed in its outer side coinmunieating with the interior of the arm. snugly and slidably held in this arm there is a stem member 42 also of rectangular form, carrying at its lower part a binding screw 43 projectedthrough the slot 41 and having an operating head therewithout. An H-shaped cross head 44 is carried at the upper end of this stem through the apertured ends of the arms of which there are slidable two rods 45, thereby maintained in a common horizontal plane, and supported upon these by suitable brackets 46 there is an arm rest 47, consisting of a plain board for the most part. A binding screw 48 is engaged in the head 44 so as to impinge on the board when the rest has been adjusted longitudinally to the desired position.

In the upper side of the arm rest two threaded sockets are provided in which screws 49 may be engaged to hold a straightedge 50 in place. This straight-edge consists of two parts hingedly connected, the outer receiving the screws 49 therethrough whereby it may be held with the joint just beyond the inner edge off the rest for vertical oscillation of the projected part, whereby it may be adjusted above or below the rest at any desired inclination. The hinge joint may be provided with any desired frictional device to prevent the swinging portion from having too free a movement. Stencils are also provided, having shanks or holders 51, constructed to slip on the outer end of the swinging piece of the straight edge to hold the stencil convenient to the hand of the operator. The base 10 is narrow for the most part, the circular portion 11 being somewhat broader, and lateral stabilizing extensions 52 are formed. at each side at its central part.

In constructing a machine my present practice is to form the shaft 19 as a cylinder, carrying in the upper end the stub 53, by means of the pin 54, the stub projecting sutliciently above the cylinder to allow proper securement of the gear 32 thereon. The extension 22 may also be formed separately if desired, although not so shown, being secured in any desirable manner to the lower end of the shaft 19.
